目前,淬火大多采用传统的工艺,例如:淬火加热温度被规定在很小的范围内;加热时间比较长;对残余奥氏体、铁素体的有害一面重视较多;各种新的淬火方法应用很少;对经化学热处理的工作只是淬火和随后的低温回火;淬火前的组织准备仍然是正火或退火等等。所有这些观点仍然支配着大多数人的行动。 At present, most of the traditional quenching process, for example: quenching temperature is specified in a very small range; heating time is longer; harmful to the retained austenite, ferrite side attention; a variety of new quenching methods Applications are few; the work of chemical heat treatment only quenching and subsequent low-temperature tempering; organizational preparation before quenching is still normalizing or annealing and so on. All these views still dominate the actions of the majority.
